Abstract: A sensor system includes a power harvesting subsystem, a control subsystem, a sensor subsystem and a communication subsystem. Electromechanical systems generate and dissipate multiple forms of waste energy as a by-product of system operation. Waste energy in the system may lead to destructive side effects which adversely affect the life of system elements. The sensor system is powered above a predetermined level and communicates the sensed information to a remote processor for system diagnosis.
